DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3This application is described in further detail.

[0033] The present application embodiment discloses a heating covering device for optical adhesive, referring to Figure 1 , including a frame 1, on which a first discharging mechanism 2, a second discharging mechanism 3, a dust removal mechanism 4 and a superposition mechanism 5 are arranged. The first discharging mechanism 2 is located at the top of the frame 1 and is used to automatically discharge the coil of the product to be covered. The second discharging mechanism 3 is located at one side of the first discharging mechanism 2 and is used to automatically discharge the optical glue. The dust removal mechanism 4 is located below the first discharging mechanism 2 and is used to perform dust removal operations on the conveyed product to be covered. The superposition mechanism 5 is located below the dust removal mechanism 4 and is used to superimpose the conveyed optical glue on the surface of the conveyed product to be covered. A heating element is arranged in the superposition mechanism 5. The heating element softens the product to be covered and the optical glue in the superposition and covering process so that the optical glue can be more closely attached to the surface of the product to be covered. At the same time, the dust removal mechanism 4 removes impurities on the surface of the product to be covered, and it is difficult to generate bubbles or wrinkles between the product to be covered and the optical glue, which is beneficial to improving the covering quality.

[0034] Reference Figure 1 and Figure 2 The first discharging mechanism 2 includes a first discharging roller 21 and a first tensioning roller 22. One end of the first discharging roller 21 and the first tensioning roller 22 are both horizontally rotatably connected to the frame 1, and the first discharging roller 21 is parallel to the first tensioning roller 22. The product to be covered is rolled on the first discharging roller 21, and the product to be covered conveyed from the first discharging roller 21 passes through the first tensioning roller 22 and then enters the overlapping mechanism 5 to realize the discharging operation of the product to be covered.

[0035] Reference Figure 1 and Figure 2 The frame 1 is provided with a support assembly 8 for supporting the other end of the first discharge roller 21. Specifically, the support assembly 8 includes a lifting cylinder 81 and a support block 82. The lifting cylinder 81 is vertically fixedly connected to the frame 1, and the support block 82 is fixedly connected to the piston rod of the lifting cylinder 81 located above it, and the support block 82 is located directly below the other end of the first discharge roller 21. When the piston rod of the lifting cylinder 81 is stretched, the piston rod of the lifting cylinder 81 pushes the support block 82 to move vertically upward, so that the support block 82 abuts against the end of the first discharge roller 21, thereby playing a supporting role for the first discharge roller 21. When it is necessary to change the material of the product to be covered on the first discharge roller 21, the piston rod of the lifting cylinder 81 contracts to drive the support block 82 to move vertically downward, so as to facilitate the change of the material of the product to be covered on the first discharge roller 21.

[0036] Reference Figure 1 and Figure 2The dust removal mechanism 4 includes a dust removal roller 41 and a winding roller 42. The dust removal roller 41 and the winding roller 42 are both rotatably connected to the frame 1. The dust removal roller 41 and the winding roller 42 are both parallel to the first discharge roller 21. The dust removal roller 41 is rolled with a tape. The tape on the dust removal roller 41 is wound on the winding roller 42. In this embodiment, the tape is a double-sided tape. The dust removal roller 41 is located below the discharge direction of the first discharge roller 21. The product to be coated delivered from the first discharge roller 21 is wound around the tape on the dust removal roller 41 and then around the first tensioning roller 22 to perform dust removal on the surface of the product to be coated. It should be noted that the surface of the product to be coated that contacts the tape is the surface that contacts the optical adhesive.

[0037] Reference Figure 1 and Figure 2 The second discharging mechanism 3 includes a second discharging roller 31 and a second tensioning roller 32. One end of the second discharging roller 31 and the second tensioning roller 32 are horizontally rotatably connected to the frame 1, and the second discharging roller 31 and the second tensioning roller 32 are parallel to the first discharging roller 21. The optical film is covered on the second discharging roller 31. The optical glue transported from the second discharging roller 31 passes through the second tensioning roller 32 and then enters the overlapping mechanism 5 to realize the discharging operation of the optical glue.

[0038] Reference Figure 1 and Figure 2 The overlapping mechanism 5 includes two support seats 51, an upper pressing roller 52 and a lower pressing roller 53. The two support seats 51 are fixedly arranged on the frame 1 and are arranged opposite to each other on the same horizontal plane. The upper pressing roller 52 and the lower pressing roller 53 are both arranged horizontally, and the upper pressing roller 52 and the lower pressing roller 53 are both parallel to the first discharge roller 21. The two ends of the upper pressing roller 52 are respectively rotatably connected to the two support seats 51, and the two ends of the lower pressing roller 53 are respectively rotatably connected to the two support seats 51. The upper pressing roller 52 and the lower pressing roller 53 are arranged to rotate in parallel and face each other. The pressure roller 52 is located above the lower pressure roller 53. There is a gap between the upper pressure roller 52 and the lower pressure roller 53 for the product to be covered and the optical adhesive to pass through, so that the product to be covered and the optical adhesive can be overlapped and pass through the gap between the upper pressure roller 52 and the lower pressure roller 53 to achieve overlapping and covering. It should be noted that the first tensioning roller 22 is located between the dust removal roller 41 and the upper pressure roller 52. The product to be covered delivered from the first discharge roller 21 passes through the dust removal roller 41 and the first tensioning roller 22 in sequence and then enters the gap between the upper pressure roller 52 and the lower pressure roller 53. At the same time, a heating element is arranged inside the upper pressure roller 52 or the lower pressure roller 53 to soften the product to be covered and the optical adhesive to be overlapped and covered, so as to improve the tightness of the overlapping and covering of the product to be covered and the optical adhesive.

[0039] Reference Figure 1 and Figure 2, the heating element is set as a heating wire (not shown in the figure), and the heating wire is arranged in a threaded shape along the length direction of the upper pressing roller 52 or the lower pressing roller 53 to improve the uniformity and stability of heating. In this embodiment, the heating wire is arranged inside the upper pressing roller 52. In addition, a sensor 6 is arranged on the frame 1, and the sensor 6 is close to the entrance between the upper pressing roller 52 and the lower pressing roller 53 in the overlapping mechanism 5 to monitor whether the upper pressing roller 52 and the lower pressing roller 53 overlap and penetrate the product to be covered and the optical adhesive. At the same time, the sensor 6 is electrically connected to the heating element. When the sensor 6 detects that the product to be covered and the optical adhesive overlap and pass through the gap between the upper pressing roller 52 and the lower pressing roller 53, the sensor 6 sends an electrical signal to the heating wire to perform heating operation. When the sensor 6 does not detect that the product to be covered and the optical adhesive overlap and pass through the gap between the upper pressing roller 52 and the lower pressing roller 53, the sensor 6 stops sending an electrical signal to the heating wire, and the heating wire does not heat up, so as to control the heating operation of the heating wire.

[0040] Reference Figure 1 and Figure 3 The support seat 51 is provided with an adjusting mechanism 7 for adjusting the gap width between the upper pressing roller 52 and the lower pressing roller 53 to be suitable for overlapping and covering operations between products to be covered with optical adhesives of different thicknesses. Specifically, the adjustment mechanism 7 includes an adjustment block 71, a screw 72 and a knob 73. The support seat 51 has a receiving cavity for accommodating the adjustment block 71 and the screw 72. The two opposite side walls of the adjustment block 71 abut against the two opposite cavity walls of the receiving cavity. The adjustment block 71 is vertically slidably connected to the inside of the support seat 51. The screw 72 is vertically threaded downward from the upper end of the support seat 51 into the receiving cavity and is rotatably connected to the top of the adjustment block 71. The knob 73 is fixedly connected to the top of the screw 72. The end of the upper pressure roller 52 is rotatably connected to the side wall of the adjustment block 71. When the staff drives the screw 72 to rotate through the knob 73, the rotating screw 72 drives the adjustment block 71 to move vertically up and down. The adjustment block 71 that moves vertically up and down drives the upper pressure roller 52 to move vertically up and down to achieve the change of the gap width between the upper pressure roller 52 and the lower pressure roller 53. It should be noted that the adjustment mechanism 7 is provided with two groups, and the two groups of adjustment mechanisms 7 respectively adjust the two ends of the upper pressure roller 52 synchronously.

[0041] The implementation principle of a heating covering device for optical adhesive in an embodiment of the present application is as follows: after the product to be covered is conveyed out from the first discharge roller 21, it successively passes through the dust removal roller 41 and the first tensioning roller 22, and then penetrates into the gap between the upper pressure roller 52 and the lower pressure roller 53; after the optical adhesive is conveyed out from the second discharge roller 31, it passes through the second tensioning roller 32, and then penetrates into the gap between the upper pressure roller 52 and the lower pressure roller 53; the product to be covered and the optical adhesive are overlapped and pass through the gap between the upper pressure roller 52 and the lower pressure roller 53; the upper pressure roller 52 and the lower pressure roller 53 rotate towards each other so that the product to be covered and the optical adhesive are overlapped and covered; during the process of overlapping and covering the product to be covered and the optical adhesive, the heating wire generates heat to soften the product to be covered and the optical adhesive, thereby facilitating the tightness of overlapping and covering the product to be covered and the optical adhesive; at the same time, the adhesive tape removes impurities on the surface of the product to be covered, and it is difficult for bubbles and wrinkles to be generated between the product to be covered and the optical adhesive, thereby facilitating the improvement of covering quality.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
